I think it's important to add that this guy, fit as he is- is giving into his fidgety-ness by leaving the room, etc. At least for a public broadcast of a Bikram class, one needs to present the concept that part of the practice is limiting the urges to move around more than necessary, leave the room, drink water between every pose, etc. Though it's completely acceptable, it's not encouraged. Part of the 'tapas' is breathing through the urges to do anything except focus on breath and the asana.
